(Cl'. 153- 1 This invention relates toa ring book assembling; machine particularly adapted to clinch tongues projecting from one book part against another part with which the first part is to be associated.

' It is an object of thisinvention to provide simple and efiicient means for securing ringgmetals to the back plate in the manufacture of; ring books. It is a further object of thisinvention to provide such means that may be easily and quick-" ly adjusted to work on any size binderjandon any size ring metal.

description taken in conjunction'with theaccompanying drawings in which:

Figure 1 is a perspective view of theinachine' with a ring book in position with parts broken away to facilitate illustration of the structure;

Figure 2 is a longitudinal sectional. view of they machine shown in Figure 1; v

Figure 3 is a cross sectional View taken along the line IIIIII of Figure 2 looking in the direction of the arrows with the book removed; and

Figure 4 is a cross sectional View taken along the line IV-IV of Figure 2 lookingin the direction of the arrows.

In the drawings, thereference numeral 2 indicates a foundation bed for the machine which is supported on any suitable table or bench 3. The foundation bed and table are cut away, as

' indicated at 4 and 4'. to provide'a space for a pinion gear 5. The member2 iscutawayyas in:

gear 5.

to, is secured to the free end of theshaft in any suitable manner. It willbe understood that the 0 shaft 8 may be driven by any suitable motor.

4 A guide channel 12 is disposed longitudinally of the foundation member 2. The guide channel is cut away, as indicated at 13, to register with the recesses 4 and 4 in the foundation member 5 and table. A slide member 14 fits within the -guide channel 12. A rack 15 disposed centrally of the under surface of the slide member 14 has its teeth in engagement with the teeth on the pinion gear 5 so that rotation of the shaft 8 will 0 cause the slide member 14 to move longitudinally in the guide channel. The teeth of therack stop short of one end of the rack to provide a stop member 16 which limits the outward movement of the rack. The upper edges of the slide mem- 55 her 14 are cut away, as indicated at 17, to pro- Other objects of this invention will become apparent upon reading thefollowing vide a pair of flanges 18 of the same height as the inner sidewalls 19 of the guide channel. A pair of plate members 20, secured to the upper edges of .the'guide channel 12 by means, of bolts 21, overlap the. flanges 18 to prevent vertical movementgofgthe slide member.

r The slide member '14 is provided near one end with a stud 22having its upper portion threaded, as indicated at 23, Figure 2. A turret 24 is rotatably mounted on the stud 22. The turret is retained on the stud bymeans of a nut 25 threaded'to engage the threads 23., A washer 26 is 1004 sitionedj between the nut 25 and the turret. The turret is provided with a plurality of plungers 2'7 of various sizes. The turret may be rotated to selectively position any plunger in operative position. The plunger is maintained in operative position by means of a pin 28 fitted in a recess 29 in the under surface of the turret 24. A coiled spring 30 exerts constant force against the pin 28, to force it downwardly. The upper surface of the;-sl ide ;member 14 is provided with a plu-. ra-lity of shallowrecesses 31 in which one end of-the pin 28 is adapted to fit. The number of recesses is thesame as the number of plungers, andy-the position-of said recessesis such that wheneyerthe pin28 is positioned in any recess, one plunger is in operative position. The pressureof the spring 30 is slight enough so that the turret may be rotated to force the pin out of the recess31and into another-recess to position a difierent plunger in operative position after the nut 25 has beenloosened slightly. 7

"Atrough shaped member 32 is secured in the channel member 12in any suitable manner.v The member 32 is adaptQd to support the back of a ring .book. The; book covers are supported by means of a pair of supports; 33 mounted on suitable supporting: structure 34. The trough shaped supporting member 32 is provided with .a front gage 35 and a back gage 36. The front gage is secured in place by means of a bolt 3'7. The front gage is provided with an aperture 38, through which the plunger 27 is adapted to be projected. The position of the back gage may be adjusted to suit the length of the book being assembled. The back gage is secured in any desired position by means of the thumb screw 39.

The book parts to be assembled include a back plate having integral tongues 41 bent up at right angles therefrom. The tongues 41 project through slots 42 in a spring plate 43. The spring plate has been previously assembled with a pair of toggle plates 44, a plurality of buttons 45 adapted to keep the inner edges of the toggle plates in alignment, a plurality of divided ring members 46, and a cover plate 47.

A few turns on the handle 11 causes the plunger 27 to be projected through the aperture 38 in the front gage member and into engagement with the tongues 41. The plunger forces the ends of the tongues down tightly against the spring plate 43 to hold the book parts together securely. Preferably the gages are adjusted so that the plunger bends only one half the tongues against the spring plate. The book being assembled is then lifted from the trough and reinserted in reversed position so that the plunger may then force the rest of the tongues against the spring plate. It is believed that the parts are more securely assembled when one half the tongues are bent in one direction, and the other half in the other direction.

It will be seen from the foregoing that I have provided simple and efficient means for rapidly and securely assembling parts of ring books. If it is desired to operate on books differing in length from that for which the machine is set, itis necessary only to loosen the thumb screw 39,- move the back gage to the required position and then tighten the thumb screw. If the size of metal is changed; the nut 25 is loosened slightly, the turret 24 rotated to align the proper plunger with the front gage, and the nut 25 tightened. a

'Although I have described'a preferred embodiment of my invention in detail, it will be understood that the description thereof is illustrative rather than restrictive, as many details may be modified or changed without departing from the spirit or scope of my invention. Accordingly, I do not desire to be restricted to the exact construction described, except as limited by the appended claims.
